莺琼盆地压力预测与监控技术及应用
|
摘要
中国南海西部莺歌海、琼东南盆地(简称莺琼盆地)属高温高压盆地。只有准确地搞好钻前压力预测,搞好油气地质研究,才能确保钻井的安全。应用了多种方法进行钻前压力预测、随钻预测及随钻监控。压力预测的准确性取决于地震波速度求取或反演的精度。研究并应用了多种高精度的速度求取或反演的方法(如地震层析成像、测井约束地震波阻抗反演等)。多方法、多手段的钻前压力预测、随钻预测及随钻监控的效果是较好的。
Yingge sea and the Yingqiong basin in the west of the South China Sea is a high temperature and high pressure basin. Only through accurate pre-drilling pressure prediction and carefully geologic study, the drilling safety can be assured. Several methods have been used in pre-drilling pressure prediction, prediction while drilling and monitoring. The accuracy of pressure prediction depends on the precision of the calculation or inversion of seismic velocity. Many ways of seismic velocity calculation or inversion have been studied and used (for instance, seismic tomography and log constraint seismic wave impedence inversion etc). The results of pre-drilling pressure prediction, prediction while drilling, and monitoring while drilling are relatively good by use of mutiple methods.
